Wow!could you try those?
the NRA just had a write-up in their American Rifleman magazine.
here's the link:
i am especially interested in the performance of the mini-12 gauge.
always enjoy your tests.
I am going to give them a try.
And I want to take those .22 20grain Super Colibri for a spin too.
Might be a good trap line load for mu Ruger Single Six.
